Question

我有一个自定义的asp.net成员类我正在建立一个我有一个帮助函数的地方 GetUser（）方法用于将我的数据库中的值转换为System.Web.Security.MembershipUser对象。

private MembershipUser _converToMembershipUser(MembershipDBModel member)
    {

        System.Web.Security.MembershipUser membershipUser = new System.Web.Security.MembershipUser(
        this.Name,
        member.UserName,
        member.UserID.ToString(),
        member.Email,
        member.PasswordQuestion,
        member.Comment,
        member.IsApproved,
        member.IsLockedOut,
        member.CreationDate,
        member.LastLoginDate,
        member.LastActivityDate,
        member.LastPasswordChangedDate,
        member.LastLockedOutDate);

        return membershipUser;
    }

这是在调用上述方法时我一直得到的错误。我不知道如何解决这个问题，所以任何建议都非常受欢迎。

Answer 1

这可能不是代码问题，它是dll参考问题。

您需要仔细查看web.config中的任何“type”，“assembly”或“publicKeyToken”xml属性。最可能的原因是您错误地复制了程序集的公钥标记。我首先检查你引用System.Web程序集的任何地方，并确保公钥令牌完全正确，并且任何类型名称都没有拼写错误。

请特别检查web.config中type和add元素下的provider元素中的membership属性。此外，如果自定义成员资格类是在单独的dll中实现的，请确保您实际上是从该dll引用了正确版本的System.Web程序集。

Answer 2

错误：“给定的程序集名称或代码库无效”

您的类型属性：

type="TMTechMembershipProvider.TempMembershipProvider"

您注释行中的类型属性：

type="TMTechMembershipProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cbae438f5bab0724"

您的评论：

我倾向于同意，但这是大海捞针。这就是我认为Fusion Log Viewer用于帮助识别无法加载的内容。

sry，但哈哈：）

更新1：重新评论：

发现它很有趣，无法抗拒。没有任何伤害，也没有任何暗示，我们都去过那里。

现在更严肃地说，它似乎仍然是一个问题，特别是那条线。

让我们将它与asp.net提供者的类型行进行比较：

type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

[Provider class (including the namespace)], [dll], [Version], ...

您似乎缺少类或dll。希望能解决它，祝你好运。
